This case study focuses on the postoperative care of Edward (Ted) Williams, an 82-year-old male who underwent a bowel resection and colostomy. The assignment addresses the biopsychosocial, spiritual, and cultural impacts of the surgery, patient problems based on collected information and pathophysiology, and nursing interventions to manage ineffective breathing patterns and pain. It explores the patient's medical history, vital signs, and medications. The study also includes a discussion of two classes of drugs used to manage Ted's postoperative condition, including analgesics and ACE inhibitors, detailing their pharmacodynamics and rationale for use. The case study highlights the importance of comprehensive patient assessment, evidence-based interventions, and holistic care in the postoperative setting, with emphasis on addressing complications such as pulmonary edema and sepsis.
